Specification of Letters latent.

Application filed May 28,1921. Serial No. 173,3605.

To all whom it may camera:-

Be it known 'thatI, GEORGE MUELLER, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented new andeuseful Improvements in a Bread Pan or Oven Tray, 01 which the following is a specification. I

The invention relates to a wheeled oven or bread pan tray or carriage.

The object of the present invention is to provide a simple, durable and efficient bread I pan tray or carriage of strong and inexpensive construction designed particularly for use in connection with the bakers oven shown and described in my co-pending application No; 405,862 filed by me the 23rd day oi August, 1920, but adapted also for use in analogous or similar structures and equipped with means for adjustably sup pans or receptacles singly or better baking of the contents of the pans is obtained,

A further object of the invention is to provide'a bread pan trayor carriage of this character in which the transverse pan supi porting members will be less liable to sag to appended, it one changes in the advantages thereof. v

drawings, in which W and in which any sagging of the members .will not caues any trouble through contact with the hearth;

With these and other'objects in v1ew, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and'pointed out in the claims herebeing understood that 'varithe form, proportion, size and minor details of construction, within the scope of the appended claims, may be resorted to without departing from the spirit of the invention or sacrificing of In theflaccompanying like numerals of reference designate corresponding parts in the several figures Figure 1 is tray or carriage constructedin accordance with this invention. y I j I Figure 2 is a side elevation of thesame,

Figure 3 is an end elevation of the bread pan tray or carriage.

Figure 4: is anenlarged detail side elevation of a portion of the bread pan tray or carriage illustrating the arrangement of a plan view of a bread pan the rollers or Wheels and the means for adustably mounting the transverse pan supportlng bars or members.

Figure 5 is a transverse sectional view of I the same.

- In the accompanying drawings in which is illustrated the preferred embodimentof the invention, the bread ban or oven tray comprises in its construction a rectangular frame composed of side and end bars l gand 2 mounted'upon rollers or wheels 3 located at opposite sides of-the bread pan or oven tray and-adapted to run on oven rails tas explained in the aforesaid application. 1 The side and end .bars 1 and 2 which are connected by corner plates 5, are preferably angle bars, the s1de bars being each comvjposed of an upper horizontal flange or wing and an outer depending vertical flange or wmg, the inner flanges or wlngs 6 being Patented Feb. 28, 1922.

provided at the inner sides of the rollers or' wheels 3 to support the inner ends of the bolts 7 which constitute spindles or axles forthe rollers or wheels and which are provided with outer nuts8. The nuts may be locked on the bolts in anysuitable manner if desired. The flanges 6 are preferably tapered downwardly as shown and they are arranged. in parallelism with the outer wings or flanges of the. side bars and have their lower edges in the same horizontal plane of thepsaid outer wing or flange of the side bar. This arrangement provides a strong structure for supporting the axles or spindles 7 of the rollers or wheels 3 which are preferably flanged as shown 1n Figure 5.

The end bars or members 2 of the frame are preferably L-shaped in cross section and consist of lower horizontal flanges and front upwardly extending wings or. flanges, as clearlyshown in Figure 2 of the drawings. The corner plates 5 which are riveted or of vertical pins 11 and upper and lower nuts 12 and 13. The tubular pan supporting bars or members upon which the bread pans or baking receptacles are. placed are less members will present convex or rounded through the adjustment surfaces to the hearth and not catch thereon or injure the same when the'bread pan or oven tray is run into and removed from the oven. The pins 11' which piercethe upper and lower portions of the tubular pan supporting bars or members have threaded lower-portions 14 to receive the upper and lower nuts 12 and 13 and the upper nuts are arranged'upon the upper faces of the horizontal flanges of the side bars, or; members of the rectangular'frame and are interposed between the same and the transverse pan supporting bars or members. The upper and lower nuts of the pins 11 firmly clamp the upper and lower faces of the horizontal flanges of the side bars or members and "rigidly support the pinsin projecting position with relation tothe frame and the up per and lower openings 15 and 16 in the upper and lower portions of the tubular pan supporting bars ormembers are preferably slightly greater in diameter than the pins so that the pan supporting rods or members may be readily placed on and removed from the pins. Also it will 'be seen that by varying the thickness of the upper nut, the tubular pan supporting members may be raised and lowered and brought closer to, or spaced further from, the horizontal flanges of the side bars or members of the rectangular frame. This will enable the bottoms of the pans to be arnnged as,

closely to the hearth or bottom of. the furnace as desired and a better baking and maximum efiect of the heat of the oven'are thereby obtained. Also the pins 11 which pierce the transverse pan supporting bars or members may be fixed to the latter and the vertical adjustment maybe obtained by the raising and lowering of thepins 11 of the upper-and lower nuts and by employing upper nuts of varying thickness the bars may be brought closer to the rectangular frame of the bread pan or oven tray.

A single wheeled tray Whichis adapted to be rapidly run into and'outof abakers oven will enable a large number of pans of rolls, bread or the like to be easily handled in introducing the dough into the oven and in removing the baked bread, rolls or the like therefrom. The pans or receptacles for the bread, biscuits, or the like, are arranged between and hung from the transverse sup- .largcr or smaller nut 12 spaced tubular porting bars or members. The pan supporting bars or members may be arranged any distance apart to suit the pans and they may extend in parallelism in any direction across. the open frame. 'Also by using a on top of the flange of the side bars, the pipes or tubular members may be arranged in such a way that they will vary from one-half to one-and-onehalf inches in their adjustment. This isimportant in securing a maximum cooking or x heating effect-from a bakers oven.

Whatis claimed is z-- 1. An oven tray comprising an open -wheeled frame adapted to run into and out of a bakers -oven, and tubular pan supportlng members mounted on the frame and presentin'g convex faces to the hearth or bot-U.

tom of the oven.

2. An oventray comprising an open frame,

spaced-bread supporting bars or members mounted upon the frame,and means for securing the bread supporting bars ormemhere to the frame, said means being arranged to raise and lower the said bars or members whereby the pa-ns or receptacles may be arranged as close to the bottom orhearth of a bakers oven as desired. 5

3. .An'oven tray comprising an open frame, 5

means for adjustably connecting the barson members with the frame, said'means comprising vertical pins piercing the bars or members and havinglower threaded portions, upper and lower nutsmounted on the threaded portions of the pins and clampin the frame, theupper nuts beinginterpose between the supportingbars or members and the frame andremovable to permit-upper 'nuts of different thicknesses to be employed for varying the distance between the pan supporting bars or members and the frame.

7 An oven tray including an open frame composed of side and end bars, the side bars being provided with outer depending flanges and having relatively short spaced inner 5 flanges, axles connecting the inner and outer flanges of the side bars, rollers or Wheels mounted on the axles, and pan supporting bars or members connected by the frame.

8. An oven tray comprising an open frame,

wheels supporting the frame and adapted to run on an oven track, and pan supporting bars or members extending across the frame and having their terminals thereon and presenting lower rounded faces to the hearth or bottom of an oven.

In testimony whereof I have hereunto affixed my signature.
